Cellar drainer



Patented July 2, 1935 UNITED STA-'15131654 PATENT oFFICE- i Howard D. Yoder,v Detroit, Mich., assignor to Penberthy Injectorl Company, Detroit, Mich., a corporation of Michigan Application August 7,1933, serial No. 683,366 sciaims. (c1. s- 276) 5 level where it can be disposed of through a sewer or other drain.

Prior devices of this general type have had thev disadvantage of being less compact and much more apt to get out of order on account of various exposed moving parts which were apt tobecome clogged by floating particles or other dirt in the drainage water. It has been the practice to construct such devices in four separate units, the strainer, ejector valve, and float, besides the various pipes, levers, etc., essential to a proper co-I operation between these parts. 'Y

In order to prevent dirt, etc., clogging up the valves or interfering with the operation of the moving parts, it has been customary to place the moving parts above the water level. However, this presents the difficulty that there is a greater liability to freeze, and besides the constructionl makes the total height of the device very great, so that it cannot be used in a small sump. I-

I have now reduced this mechanism to one compact unit which may be operated in much smaller space than the ones previously made, and which overcomes the difficulties described above.

It is, then, an object of this invention to provide a cellar drainer which is more efficient and more compact than those now in use.

It is a further object of this invention to provide a drainer which has the principal moving parts protected from entanglement with foreign matter. A

Further objects of this invention will become obvious from the following specification and the accompanying claims.

As shown on the drawing:

Figure 1 represents a side elevational view. of my device installed in a sump, with the sump;

the strainer 36 and connects with any suitable source of water supply under pressure to operate the ejector mechanism. A discharge pipe 46 also extends upwardly from the ejector mechanism andl connects to any suitable drain. The entire apparatus is mounted on a base 5 which comprises a flat portion supported by legs, said flat portion having a number of posts or projections 1, I9, 2 I, 35 and 38 for supporting the various operative parts mounted thereon. -The pipe 6 is connected'with a hollow upright portion I cast integral with the base 5. An orifice II extends through one side of the portion I and opens into a conical space 9. The space 9 is normally shut off from the interior 8 of portion 'I by a valve mechanism which will now be described.

The portion 'I is provided with a large horizon- A of the conical space 9, thereby preventing communication between the spaces 8 and 9. This prevents water entering through the pipe I5 from passing through the orifice I I when the disc holder I2 is properly seated.

The position of disc holder l2 is controlled by the float 25. The connection between the iioat and the disc holder will now be described.

The plunger I3 which carries disc holder I2 extends through the packing gland I5 and carries two collars I6 and I1 between which a cam I8 is mounted on a horizontal shaft 26. The shaft 20 is supported by bearings I9 and 2I which may be cast integral with the base 5. A lever 22 is mounted near one end of the shaft 20 and is connected to abar 23 which extends upwardly into a chamber 24 within the float 25. When the float 25 rises due to anaccumulation of water around the apparatus, a flange 21 ,at the lower end of the chamber 2,4, contacts with a projection 26 on the upperend. ofthe bar 23, forcing said bar upwardly. This movementof the rbar 23 causes an upward movement of the lever 22 and a rotation of the shaft 20 and the cam I8. The cam I8 then contacts with the collar I6, forcing the disc holder I2 away from the space 9, thus allowing water within space 8 to enter space 9 and discharge through the orice I I. An ejector casing 30 is placed adjacent the orifice II. This casing 30 contains an axial opening which comprises the conical portion 3l, the cylindrical portion 32 and the enlarged portion 33.

In use, the entire apparatus is installed in a sump, as at 45, and the action just described takes place when the sump has lled with water. The stream of water from orifice I I enters the conical opening 3| of the ejector casing 30 and the decrease in pressure resulting from the motion of said stream causes a rush of water into the casing and out through the discharge pipe 46 connected thereto. f *Y This action-results in l'a graduallowering of the water level in the sump and a settling of the oat 25 until the flange 5I contacts with the pro- .iection 26. This forces the bar 23 doimyardly,

thus causing a rotation of the shaft 20 and the cam I8 which forces the disc holder-= I?" against' the opening 9, thus closing saidopenin'g andstopping,

the ejector action. As soon as sufcient water has again accumulated in sumpzli, the ohm deL-- scribed cycle is repeated.

In case my device is used on high water pressure. I prefer to place aooilsnr ing 6on`tberpii e 6 above the Vfloat 2,5 to lessen anyshocki ory lar: which might occur fronithe iioat contacting with apinc-bushing 60. placed at a predetermined height controued bythe length: of the-Dine L A- valve Imand a union 6I are providedin'theninef for convenience in Cleaning or reiiairinanni.olevioe` .Oneof the greatA advantages of this device over previous structures is the incorporation of@ the f valve mechanism withinthe strainer A strainer hasbeen necessary innrevious devices, and since the Valve was not incorporated withiniait Was-'necessary to use additional space above the strainer for the valve, and this has always resulted in amuoh less Compact and higher structure than my present invention i I am aware that many changes be made and numerous details of Construction inarbe varied through a wideranse without departing;
